To all whom it may concern.-

Be it known that I, CHARLES J AOOB GUSTAF- SON, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Self-Oiling Journal-Box, of which the following is a specification.

My invention relates to journal-boxes, such as are employed to receive and support the ends of the axle on railway-cars, and has for its object to produce a simple inexpensive device of this character designed to carry a supply of lubricant and feed the latter regularly and evenly to the journal.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side sectional elevation showing my improved journal-box applied for use. Fig. 2 is an end elevation of the same. Fig. 3 is a section on the line 3 3 of Fig. 1.

Referring to the drawings, 1 designates a car-axle having mounted thereon a wheel 2, beyond the outer side face of which the axle is extended to form a journal 3, having bearing for rotation in a journal-box 4:,- attached These parts, with the exception of the journal-box, may all be of the usual or any preferred construction and assembled in the ordinary or any desired manner.

The journal-box 4:, constituting the subject-matter of this invention, and which receives and supports the journal 3, is preferably formed of a single casting and is provided with a central enlargement 4, defining oppositely-disposed laterally-projecting seating-flanges 5, adapted to receive the longitudinal sill, said journal-box being secured to the sill 5 by means of bolts 6, which pass through perforations in the ears or lugs and engage alined openings in the longitudinal sill, as shown. The journal-box 4 is provided with a bearing-face 6, between which and the adjacent face of the journal there is disposed, as usual, a journal-brass 7, while beneath the journal and at the outer end thereof the box is cored or hollowed out to produce an oil-v chamber 8, the entrance-opening 9 of which is formed by the rearwardly-curved forward edge 8', of the enlargement 4t and the front wall of the box, said opening being normally closed by a dust-proof lid or cover 10 of the usual construction. By having the forward box and disposed beneath the journal 3, adja-' cent to the outer end thereof, the upper edge of the partition being substautiallyin contact with the surface of the journal, thus rendering said compartments to all intents and purposes practically wholly separate and distinct.

In practice the compartment 11 is filled with waste or other suitable absorbent packing material and the compartment 12 is charged with a supply of lubricant, with which latter the packing is also saturated. During rotation the journal receives upon its outer end lubricant from the compartment 12 and feeds the same over the upper edge of the partition onto the packing within the compartment 11, and the packing in turn supplies the lubricant to the face of the journal. Thus the waste is constantly supplied with and spreads the lubricant smoothly and evenly over the surface of the journal, while the latter, which as usual has a certain amount of endwise movement, is prevented from shifting or displacing the packing, owing to the latter being positively retained in place by the partition 13.

It will be observed that owing to the upper edge of the partition being arranged in close proximity to the face of the journal the oil from the supply-compartment 12 will be fed gradually to the packing in compartment 11, thereby maintaining the packing sufiiciently saturated for properly lubricating the journal, but at the same time obviating a needless waste of the lubricant, owing to an undue flow of the latter to the packing. Further, by arranging the oil-receiving compartment at the front of the journal the supply of lubricant therein may be more readily replenished, and by arranging the packing-receiving compartment at the rear of the journal the packing may be adapted for spreading lubricant upon the surface of and practically throughout the entire length of the journal.

From the foregoing it is apparent that I produce a simple inexpensive device which in practice will e'fiiciently perform its functions. In attaining these ends it is to be understood that I do not limit myself to the precise details herein set forth, inasmuch as minor changes may be made therein without departing from the spirit of the invention.

1 Having thus described my invention, what I claim is- A journal-box formed of a single casting provided with a central transversely-disposed enlargement having a curved bottom and defining opppositely-disposed laterally-projecting seating flanges having bolt receiving openings formed therein, the body of the castingbeneath said enlargement being cored or hollowed out to form an oil-Well the front wall of which is spaced from the front edge of the enlargement to form an oil-supply opening, there being an opening formed in the rear wall of the casting communicating with the oil-well for the reception of a journal, said opening being of greater diameter than that of the In testimony that I claim the foregoing as I my own I have hereto aflixed my signature in the presence-of two witnesses CHARLES JACOB GUSTAFSON,
